Getting To Know The Circles
Do you know the names of the parts of a circle? Let’s verify your knowledge 🙂
Circumference of a circle is its distance around the circle. It is also the perimeter of the circle.
Centre is in the centre of a circle. The distance from this point to any other point on the circumference is the same.
The distance from the centre to any point on the circumference is called the radius.
A chord is a straight line joining two points on the circumference.
Diameter is longest chord in a circle, passes through the centre of the circle and joins two points on the circumference.
Part of a circumference of a circle is known as an arc. The shorter one is called the minor arc while the longer arc is called the major arc.
A segment of a circle is the region enclosed by an arc and a chord of the circle. The larger segment is called the major segment while the smaller one is the minor segment.
A sector is a region enclosed by two radii and an arc. The smaller sector is called the minor sector while the larger one is called a major sector.
The line is called a tangent if that straight line and a circle have only one point of contact. A tangent is always perpendicular to the radius drawn to the point of contact.
A secant is a straight line cutting at two distinct points on the circumference of the circle.
Well, is everything verified? 🙂
